When NASA's Artemis I rocket launches into space on Monday, August 29, it will be the culmination of years of work by hundreds of people. Many of them are in the southern part of the United States, in some facilities that were originally created by NASA for the design and testing of the rockets of the Apollo program.
NASA's new moon rocket makes its first test launch without astronauts on board next week. The 100-meter-tall rocket will attempt to send an unmanned capsule into a distant lunar orbit. The launch takes place on Monday morning from the Kennedy Space Center in Florida.

If all goes well, astronaut trips could begin as early as 2024.
This will be NASA's first trip to the Moon in half a century, and the cost will exceed $4 billion. When NASA's entire program for returning astronauts to the Moon is completed, the cost will have reached $96 billion.
It will be the culmination of years of work by hundreds of people.
"This was not the work of one or two people. Here were teams of hundreds of people who came together from different fields, different experiences that made it possible to do this together," says Nicholas Nugent, design engineer at the Stennis Space Center.
Many of them are in the southern part of the Gulf of Mexico and work scattered in several facilities that NASA originally set up for the Apollo mission.
"We will launch the rocket that these people built. Isn't that fantastic? They can say 'I worked on this rocket,' and they're going to work on the second, third, fourth and fifth,” says Lonnie Dutreix, director of NASA's New Orleans facility.
Over 50 years later, the Apollo mission still stands out as NASA's greatest achievement.
Using technology from the 1960s, just eight years after sending the first astronaut Alan Shepard, NASA managed to land astronauts Neil Armstrong and Buzz Aldrin on the moon.
While it took at least a decade of work to prepare the new Artemis rocket, although there was also the experience created by an exploration program on the Moon, which was called Constellation, but that did not last long. 12 astronauts of the Apollo mission walked on the surface of the Moon during the period 1969-1972, with a stay of no longer than three days for each.
The new Artemis rocket is shorter and thinner than the rocket that sent a total of 24 astronauts to the moon half a century ago. However, it is more powerful. Its future versions, to be called the Space Launch System, will be even bigger.

To staff the Artemis rocket, NASA will select from among 42 astronauts who will be able to stay on the Moon for at least a week.
The objective is to establish a long-term presence on the Moon that will prepare the ground for sending humans to Mars.
